使用管桩余浆生产发泡混凝土

Preparation for Foam Concrete by Using Residual Paste from Concrete Pile

研究了使用管桩生产过程中产生的余浆作为主要原材料生产发泡混凝土的性能。结果表明,使用纯余浆作为胶凝材料时,制定合适的制备工艺,可以制备出性能较好的纯余浆发泡混凝土;在余浆中添加一定量的水泥,使制备的发泡混凝土密度控制在300kg/m3左右,强度可达到0.5MPa以上。

Using the residual paste generated from concrete pile production process as main material for the produc-tion of foam concrete, and determining its relative performances are studied in this paper. The results show that using pure residual paste as cementitious material and making proper preparation technology can produce the good pure residual paste foam concrete. And adding a certain amount of cement in residual paste can produce foam concrete with the density about 300kg/m3, and the strength more than 0.5MPa.
